PT Freeport Indonesia has set a target of early 2028 to restore full production at its Grasberg copper mine, one of the world’s largest, following a debilitating mudflow accident last year. President Director Tony Wenas confirmed the timeline, aligning with a revised schedule from minority shareholder Freeport-McMoRan (NYSE: FCX), which now projects a return to 100% capacity by the end of 2027.
The Grasberg complex in Central Papua, currently operating at just 40% to 50% capacity, has faced a slower-than-expected recovery. Freeport-McMoRan adjusted its earlier targets, slashing planned sales volumes and projecting a gradual ramp-up: 65% capacity in the second half of 2026, 80% by mid-2027, and near-full output by late 2027. This delay compounds pressure on global copper supply, already strained by multiple mining disruptions last year.
Copper prices, which hit a record high in January on speculative buying, remain elevated as markets grapple with potential further constraints. A shortage of sulfur, critical for processing the metal, adds another layer of uncertainty for traders tracking supply dynamics. Grasberg’s prolonged downtime has amplified these concerns, given its historical status as the world’s second-largest copper producer.

The Indonesian government, a majority stakeholder in PT Freeport Indonesia, faces fiscal challenges from the mine’s reduced output, especially amid budgetary strains linked to the ongoing Iran conflict. In a strategic move, Jakarta extended Freeport’s operating rights in February in exchange for a 12% stake transfer in 2041, securing long-term state interest in the asset.
Delays at Grasberg have tangible implications for both local and global economies. The mine’s output shortfall continues to ripple through copper markets, where demand tied to electrification and renewable energy projects shows no sign of easing.
Freeport-McMoRan’s updated production targets underscore the scale of the challenge, with the 65% capacity mark in late 2026 serving as the next critical benchmark for assessing recovery progress.
